Lokomotiva na svoz dřeva modelové železnice v měřítku Sn3 pro železniční modeláře ve špičkové kvalitě - Samhongsa Seoul Korea West Side Lumber Co. #3 Sn3 2-Truck Heisler Logging Steam Locomotive DCC & Sound.

The Heisler locomotive features :

8 Wheel Electrical pickup! All Wheel Drive just like the prototype! Swiss Made MicroMo Motor w/Integral Gearing! Real 2:1 “Bevel Cut” “Ring and Pinion” Geared Trucks! Real Driveshaft and “U” joints just like the prototype! “Quartered” Sound Cam hidden on the Driveshaft! Stainless Steel Driver Tires! “CNC” Cut, Pre-Blackened Trucks for Precise Fit! Operating Genuine Kadee ® Couplers!

The great versatility of this type of locomotive, rendered it also a wise choice for use in dockside operations; on service tracks that linked deposits also to the exterior of urban areas. The other common use of this loco was in the actual forests where, tree logging was being done.

Any modeler worth his salt who studies the likes of the "Geared Locomotive" can tell you there are basically three different types of them - Shays, Heislers and Climaxes. (Willamettes were merely Shay knock-offs ...) Of these three type, by far the most popular was the Shay.

It might be said that Shay s only real threat came from the Heisler, manufactured by the "Stearns Manufacturing Co. of Erie Pennsylvania. And although the Climax never put much of a dent in the sales of the Shay locomotives, it is design, and surprisingly, that of the Heisler were both patented by the same fellow, a Mr. George Gilbert.

The first true Heisler bearing that name appeared in August of 1894. The prototypes No. #2 and #3 rolled out of Stearn s Erie plant only a few years thereafter: 1899 and 1900 respectively. And, unbelievable as it may seem, both survive to this day! #2 in rather shoddy condition in the "Tuolumne City Park" in Tuolumne California; #3 in magnificently restored, fully operating condition in Felton California where she is operated on a regular basis on the 6% (and greater) grades of the railroad lines! Now with scale top speeds in the low "teens" there is just no stopping them!

There exists the three truck engine with an added powered tender, thus a three powered bogie. Thus increased traction, compared to the initial two bogied version, without increasing the specific axel weight, which is an important detail, which lets the loco transit on bridges, viaducts, and lines with limited track/axle /weight ratio.

In the locomotive all two bogies are powered with transmission with external rods like in the original. All gearings are functional; as so are the lamps, one on the front of the boiler, and the other on the roof of the cabin.

Of “geared" locomotives there are three types: Shay, Climax, Heisler. All have a «body» boiler driver’s cabin and coal and water deposit all on one chassis with geared transmission to the wheels, thus the name “geared locomotive”.

The steam engine is different on all three of the models, just as, is its position on the chassis. In any case is it a locomotive with a high revolutions, which is linked by a transmission geared to reduce and powering the driving wheels which are of a smaller size than normal, and since all wheels are powered this produces high power of traction, low speed, and give the loco excellent traction grip. The loco therefore is ideal for high gradient track, tight corners, and tortuous tracks, where a normal Locomotive with a rigid chassis and main driving rods could not operate.

On the Heisler type the body of the Loco lies on two or three bogies with four wheels each, the motor in centrally positioned with its two cylinders in a V 90° configuration. The main transmission shaft is positioned longitudinally to the chassis , and lets the loco move via an articulated transmission shaft that drives a cone toothed pinion on a crowned pinion at the centre of the axles on each of the bogies. This axle moves the one next via linkage rods on the exterior of the wheels..

American Geared Locomotives - Historical Background:

Driving normal fixed frame locomotive on logging railways was virtually impossible. The irregular underground made the wheels come off the track and derailed the locomotive. One of the solutions to this problem, among the more numerous Shay and Climax was the Heisler.

The Heisler distincts itself by its V-shaped two cylinder steam engine, driving a central crank shaft which on its turn drove one axle of each powered truck. The other axle was driven through a conventional rod.

Like so many technological advancements, invention is often derived from need. These interesting geared locomotives were conceived and designed by men working on site and looking for better ways to transport logs as quickly as possible on temporary rails over rough terrain. Ephraim Shay was one of these men and the story starts with him.

The Heisler Locomotive:

The first locomotive of the Charles Heisler design was built in 1891 by the Dunkirk Engineering Company. The design was patented by Charles Heisler in 1892.

The Heisler consisted of 2 steam cylinders positioned in a "V" under the boiler about 3/4th the way back from the front. The piston rods came out of the cylinders and attached to a "crank shaft" located under the centre of the boiler. Attached to either end of the crank shaft were drive shafts. The drive shafts were located below the centre line of the engine. On the two truck models, the drive shaft attached to a gear box located on each truck s wheel set that was located furthest from the centre of the engine frame. Power was then supplied to the other wheel set on the truck with an outboard tie rod connecting two wheel sets together. This tie rod is readily visible in the picture above.

In terms of speed, it was the fastest of the 3 most prevalent geared steam locomotives depicted here. It also had the fewest numbers manufactured of these type of locomotives.

Models with either two or three truck sets were manufactured. The three truck models were used on those engines that required more power and more fuel. The third truck was powered and carried a tender (similar to those on "rod" engines) to carry additional fuel and water.

Rivarossi produced two Heisler Locomotive models, a two truck and a three truck version.

The Bachmann HO scale range consists of HO scale models from North America. HO are 1/87 scale models, running on the same 16.5mm track gauge as OO scale models. The Spectrum range are also HO and N Scale American prototypes but feature a greater level of detail and improved mechanisms.

Rivarossi has produced the Heisler in two truck wood burning and oil burning models with the following liveries: McCloud River, Georgia Pacific, Coos Bay Lumber, West Side Lumber Co., Potlach, Pickering and Boise Cascade. The model was produced as a three truck model for Lehigh Navigation Coal Co, St. Regis Paper Co. and Cass Scenic Railway.

Rivarossi Two Truck & Three Truck Steam Heisler HO Scale:

These models were first produced in the 80s and then updated at the end of 2002. In 2003, Lima was forced into liquidation and in October 2004 Hornby acquired the assets of Lima, including Rivarossi.

These Rivarossi models, produced in the early 2000s are made with an all-new body that completely eliminates moulded-on detail. All of the piping, sand lines, air lines, and more are separate details. Blackened wire grab irons and handrails add to the realistic effect. There is also a solid-brass whistle, pop valves, bell, front number plate and photo-etched builders plates. And check out the other new features like flush-fitting cab windows, optional headlight styles and working knuckle couplers.

Inside that beautiful body lurks a tough, new drive that works like a real Heisler! A can motor and new gearbox are connected to a super replica of the V-2 "motor engine," so the crankshaft, rods and valve gear move like the originals.

Driveshafts transmit power to solid-metal worm gears on one axle, and side rods power all of the wheels just as the prototype did. Best of all, the models are DCC-ready so you can plug in your favourite decoder and start running.

A larger weight and an optional traction-tire-equipped driver set are included to improve pulling power. Plus, the trucks have been carefully engineered to provide all-wheel electrical pickup and still take incredibly sharp curves with ease.

Perfect for any industry from logging to coal mining to industrial switching these new models are offered in both 2 and 3 Truck versions. Each is fully assembled and factory painted. Various road names are available.

The Rivarossi 3 Truck model depicts a large standard gauge three truck machine, and is quite impressive.

The underlying shell is enhanced with many added details- fine black wire handrails, coupler cut bars, air brake pump, reservoir, and piping, with the smoke box number plate, bell, whistle and safety vales in brass.

The working motion is a treat and the model is powered from a motor in the cab and bunker which drives the trucks using the central drive shaft with universal joints, as per proto type; the gearbox is hidden in the firebox. The loco sports a good plain satin black finish with dark graphite smoke box.
